In a pie eating contest, a
participant eats 4 pies in 15
minutes. At this rate, how many
minutes will it take the participant
to eat 20 pies?
Answer:
75 minutes
Step-by-step explanation:
Make an equation
4 pies to 15 minutes = 20 pies to x minutes
4 / 15 = 20 / x
Now cross multiply
4x = 15 × 20
And multiply 15 and 20
4x = 300
Then divide both sides by 4
x = 75
So your answer is 75 minutes

O infinite number of solutions
The solution is, x = 0 , y = 4, solutions that this linear system of equation have.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
Solve the following system:
{y = 4 - 3 x | (equation 1)
x + 2 y = 8 | (equation 2)
Express the system in standard form:
{3 x + y = 4 | (equation 1)
x + 2 y = 8 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 x + y = 4 | (equation 1)
0 x+(5 y)/3 = 20/3 | (equation 2)
Multiply equation 2 by 3/5:
{3 x + y = 4 | (equation 1)
0 x+y = 4 | (equation 2)
Subtract equation 2 from equation 1:
{3 x+0 y = 0 | (equation 1)
0 x+y = 4 | (equation 2)
Divide equation 1 by 3:
{x+0 y = 0 | (equation 1)
0 x+y = 4 | (equation 2)
Collect results:
Answer: {x = 0 , y = 4
Hence, The solution is, x = 0 , y = 4, solutions that this linear system of equation have.

Answer:
84 = j × 7
Step-by-step explanation:
A product results from multiplying two numbers. Here, the two numbers are said to be "Julie's score" and 7. "Julie's score" is represented by j, so the product is ...
j × 7
Then the translation can be ...
84 is the product of j and 7
84 = j × 7
__
In algebra, we can indicate a product without the multiplication symbol, simply by writing the factors next to each other. Generally, we write the numeric factor first:
84 = 7j . . . . another way to write the answer

A marketing agency selected a random sample of television viewers to test the claim that the proportion of viewers who watch a particular show is less than 0.20 at a level of significance of 0.05. The test yielded a p-value of 0.47. Assuming all conditions for inference were met, which of the following is the correct conclusion?
a. At the level of significance of 0.05, the null hypothesis is not rejected. There is not convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20
b. At the level of significance of 0.05, the null hypothesis is not rejected. There is convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20.
c. At the level of significance of 0.05, the null hypothesis is rejected. There is convincing evidence to suggest that the true proportion of television viewers who watch the show is less than 0.20.
d. At the level of significance of 0.05, the null hypothesis is rejected. There is not convincing evidence to suggest that the true proportion of television viewers who watch the show is greater than 0.20.
e. At the level of significance of 0.05, the null hypothesis is rejected. There is convincing evidence to conclude that the null hypothesis is true.
Answer:
A) At the level of significance of 0.05, the null hypothesis is not rejected. There is not convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20.
Since the calculated p value by the test is obtained higher than that of significance level, thus we cannot reject the null hypothesis.
Thus, option A: At the level of significance of 0.05, the null hypothesis is not rejected. There is not convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20.
We have following information:
The p value obtained by test = 0.47
The test was conducted to test the claim that the proportion of viewers who watch a particular show is less than 0.20 at a level of significance 0.05.
How do we test the hypothesis?We have the null hypothesis as
Null hypothesis here = "the proportion of viewers who watch a particular show is equal to 0.20 "
Alternate hypothesis = "the proportion for aforesaid condition is less than 0.20"
Since the obtained p value is more than the level of significance, thus we have the conclusion that we cannot reject the null hypothesis, thus cannot conclude that the proportion for aforesaid condition is less than 0.20.
Thus, option A: At the level of significance of 0.05, the null hypothesis is not rejected. There is not convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20.

Your gym membership costs $25 per month after an initial membership fee. You paid a total of $215 after 7 months. Find the total cost after
12 months.
Answer: Total cost after 12 months is $
Answer:
$340
Step-by-step explanation:
$215 after 7 months including initial membership fee
$25 per month
A year has 12 months, so it's 5 months more than 7 months.
You need to find the price of 5 months and add to the price of the first 7 months that already includes the initial membership fee.
$25/month * 5 months = $125
The extra 5 months cost $125.
$215 + $125 = $340

40% of 115 is what number
Answer:
46
Step-by-step explanation:
first multiply 115 by .40 then you got your answer
Answer:
46
Step-by-step explanation:
First, we will convert the text, 40% of 115 is what number, into a math equation, 40% * 115 = x. To get rid of the % sign (who like those?) we will multiply both sides by 10. 4 * 115 = 10x. Simplifing, we get 460 = x. So, x = 46

A particle traveled a distance of 9.0×1012 meters at a rate of 1.8×105 meters per second. If distance = rate x time, how many seconds did it take the particle to travel the specified distance?
Answer:it took the particle 50,000,000 seconds to travel the specified distance
Step-by-step explanation:
Given that distance = Rate x time
Distance traveled by Particle= 9.0×10^12 meters
and rate= 1.8×105 meters per second
Time taken for particle to travel the specified distance using our equation that
distance = Rate x time
time = Distance / Rate
=9.0×10^12 meters/ 1.8×105 meters per second
=50,000,000 seconds

An equilateral triangle has a side length of 40.
Another side of the same triangle measures 3x + y.
The third side of the same triangle measures 4x - 2y.
What are the values of x and y that would keep the triangle equilateral?
Answer:
x=12
y = 4
Step-by-step explanation:
3x + y = 4x - 2y
x = 3y
y= 1/3x
3x + y = 40 3x + y = 40
3(3y) + y = 40 3x + (1/3x) = 40
9y + y =40 10/3x = 40
10y = 40 x = 12
y= 4
Answer:
We know that all sides of the equilateral triangle is equal.
Given :---
An equilateral triangle has a side length of 40.
Another side of the same triangle measures
3x + y.
The third side of the same triangle measures
4x - 2y.
According to the above problem, the equation are
3x+y=40........(i) and 4x-2y=40.........(ii)
Divide the equation (ii) by 2, we get
2x-y=20..........(iii)
Now solving for x and y we get,
3x+y=40.......(i)
2x-y=20........(iii)
5x =60
x=60/5
x=12
Putting the value of x in equation in equation (iii) we get
24-y=20
y=24-20
y=4
The values of x and y that would keep the triangle equilateral are 12 and 4 respectively.
Hence, the value of x is 12 and y is 4.jessica I have sent u letter in email did u read it?

Answer:
$63
Step-by-step explanation:
Find out the total amount of units that Jack and Molly have.

11 units = $77
Find out 1 unit to be able to find out how much Evan receives.
1 unit = $77 ÷ 11 = 7
Evan has 9 units, so find out how much money is 9 units.
9 units = 7 x 9 = $63

a mechanic rotates the octagonal nut shown clockwise about its center, what is the angle of rotation that moves position 8 to position 5?
Answer:
[tex]Total\ Rotation = 225^{\circ}[/tex]
Step-by-step explanation:
Given
See attachment for nut
Required
Determine the angle of rotation
The total angle in the nut is:
[tex]\theta = 360^{\circ}[/tex]
An octagonal nut has 8 sides. So, each rotation is:
[tex]Each\ Rotation=\frac{360^{\circ}}{8}[/tex]
[tex]Each\ Rotation=45^{\circ}[/tex]
From position 8 to 5, there are 5 movements.
So, the total rotation is:
[tex]Total\ Rotation = Each\ Rotation * Moves[/tex]
[tex]Total\ Rotation = 45^{\circ} * 5[/tex]
[tex]Total\ Rotation = 225^{\circ}[/tex]
